I know it's a bit late to reply to this topic but here is how to work it out for anyone that might be interested. This answer is based on the assumption that you are mixing roughly 5 cups hot liquor to one pound of grain during dough-in.

The keg has a diameter of 15.5in which means that the cross section has an area of 188.7in² using the formula: A = Pi * r²
